Description

Technical Field

[0001] The present application relates to the technical field of tool carts, and in particular to a tool cart for offshore platforms. Background Art

[0002] An offshore platform is a structure that provides production and living facilities for offshore activities such as drilling, production, transportation, observation, navigation, and construction. It collectively refers to mobile and fixed platforms used for offshore oil and gas exploration and development. It consists of a superstructure, facilities and equipment, and supporting structures.

[0003] When the offshore platform encounters severe weather at sea, it will shake to a certain extent. When the equipment on the offshore platform needs to be repaired, the staff will push the tool cart to the designated area to repair the equipment. In order to facilitate transfer, the tool cart on the offshore platform is generally a hand-push tool cart, including a cabinet for storing tools and a push handle installed on the cabinet, and universal wheels are installed on the bottom of the cabinet. However, this hand-push tool cart is prone to self-movement due to the shaking of the offshore platform during use, which not only affects the normal maintenance of the staff, but the self-moving tool cart is also prone to injuring the staff and equipment on the offshore platform, posing a certain safety hazard. Although the universal wheels on the existing hand-push tool carts are self-locking, the staff need to step on the brake pedals on the universal wheels during maintenance, which is inconvenient to use.

Implementation Method

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0028] like Figure 1-Figure 7As shown, an embodiment of the present application proposes a tool cart for an offshore platform, comprising a mobile cabinet 1. The mobile cabinet 1 is an existing mobile tool cart, comprising a cabinet and four universal wheels mounted on the bottom of the cabinet. A push handle is mounted on one side of the cabinet. Preferably, the cabinet door and the drawer for placing tools on the cabinet are equipped with a flat lock, which can prevent the door and the drawer from sliding out of the cabinet when closed. A connecting plate 2 is rotatably mounted on the bottom of the mobile cabinet 1, that is, the side of the cabinet equipped with the universal wheels. The bottom surface of the connecting plate 2 is open and the internal rotation A rotating disk 3 is installed on the rotating disk 3, and a plurality of rotating frames 4 are installed on the bottom of the rotating disk 3 in a circular array. The rotating axes of the rotating frames 4 and the rotating disk 3 are both vertical. A rotating wheel 5 is installed on the rotating frame 4. The rotating wheel 5 contacts the ground with the universal self-locking wheel. When the mobile cabinet 1 is moving, the rotating disk 3 and the rotating frame 4 will rotate with the moving direction of the mobile cabinet 1, so that the moving direction of the rotating wheel 5 is consistent with the moving direction of the universal wheel on the cabinet. A locking plate 6 is installed on the rotating frame 4, and a transmission member 7 is installed between the rotating wheel 5 and the locking plate 6. When the movable cabinet 1 is in use, the locking plate 6 is moved by the transmission member 7. A speed limiting member 8 is installed on the rotating frame 4 to act on the locking plate 6. When the marine platform shakes due to bad weather, the movable cabinet 1 slides on the marine platform. Because there are multiple tools placed inside the movable cabinet 1, the tools and the cabinet itself have a certain weight when moving. Therefore, the movable cabinet 1 will move faster and faster, so the rotating wheel 5 will rotate faster and faster. At this time, the locking plate 6 will slide faster and faster through the transmission member 7. When the locking plate 6 slides to a certain speed, the sliding position of the locking plate 6 can be limited by the speed limiting member 8, thereby indirectly stopping the rotating wheel 5 from moving, so as to achieve a self-locking effect, thereby forming multiple rotating wheels 5 rubbing against the marine platform, thereby delaying or stopping the movement of the movable cabinet 1 by friction, thereby preventing the movable cabinet 1 from hitting the staff and damaging other equipment on the marine platform, thereby improving safety, and no staff needs to step on the brake plate on the universal wheel, which is more convenient to use.

[0029] like Figure 1 、 Figure 2 and Figure 7As shown, in some embodiments, the rotating wheel 5 is rotatably mounted on the rotating frame 4 through the mounting rod 9; the transmission member 7 includes a rotating disk 701 and a connecting rod 702, one end of the mounting rod 9 passes through the rotating frame 4 and is coaxially connected to the rotating disk 701, the connecting rod 702 is eccentrically hinged on the rotating disk 701, and the free end of the connecting rod 702 is hinged on the locking plate 6. When the rotating wheel 5 continues to rotate, because the mounting rod 9 on the rotating wheel 5 is connected to the rotating disk 701, the rotating disk 701 will also rotate accordingly, and the rotation of the rotating disk 701 drives the connecting rod 702 eccentrically hinged thereon to move. Because one end of the connecting rod 702 is hinged on the locking plate 6, the rotation of the rotating disk 701 will cause the locking plate 6 to continue to move back and forth, so when the locking plate 6 is limited by the speed limiter 8, the wheel will also stop moving, thereby serving as a brake to stop the movable cabinet 1.

[0030] like Figure 1 、 Figure 2 、 Figure 5 and Figure 7 As shown, in some embodiments, a mounting groove 801 is opened on one side of the locking plate 6 along its sliding direction, the speed limiter 8 includes a plurality of linear array drive posts 802 mounted in the mounting groove 801, a drive rod 803 is rotatably mounted on the rotating frame 4, and a plurality of drive card plates 804 are constructed in a circular array on the outer periphery of the drive rod 803. The drive rod 803 is engaged with the plurality of drive posts 802 through the drive card plates 804, and a connecting shaft 805 is rotatably mounted on the rotating frame 4. The upper sleeve is provided with a torsion spring 806, one end of the torsion spring 806 is connected to the rotating frame 4, and the other end of the torsion spring 806 is connected to the connecting shaft 805. The outer peripheral side of the connecting shaft 805 is symmetrically structured with a limit plate 807, and the connecting shaft 805 is provided with a driving plate 808 located between the two limit plates 807. A limit block 809 in contact with the limit plate 807 is installed on the rotating frame 4, and the limit block 809 is constructed with two contact surfaces 8010, which are respectively used to contact the two limit plates 807. Figure 7As shown, when the locking plate 6 continues to move vertically back and forth, it will drive the driving column 802 installed in the installation groove 801 to move. Because the driving rod 803 is engaged with the driving column 802 through the driving card plate 804, thereby forming a gear rack engagement transmission type, the driving rod 803 will continue to rotate forward and reverse. As the driving rod 803 rotates, the driving card plate 804 on the driving rod 803 will contact the limit plate 807 on the connecting shaft 805, thereby causing the driving plate 808 to rotate, thereby causing the connecting shaft 805 to rotate a certain angle. When the movable cabinet 1 is pushed normally, the rotation of the driving rod 803 causes the driving card plate 804 to contact the driving plate 808, and the connecting shaft 805 will rotate along with it, and the torsion spring 806 is in a torsion state. When the driving card plate 804 is separated from the driving plate 808, it is automatically reset by the elastic deformation of the torsion spring 806, thereby causing the driving plate 808 remains horizontal and in contact with the next driving card plate 804, thereby preventing the roller from rotating. However, when the roller rotates too fast, after the driving card plate 804 is disconnected from the driving plate 808, the torsion spring 806 has not yet reset, which causes the next driving card plate 804 to contact one of the limit plates 807, thereby causing the connecting shaft 805 to continue to rotate through the limit plate 807. At this time, the other limit plate 807 will contact one of the interference surfaces 8010 on the limit block 809, thereby stopping the connecting shaft 805 from rotating, causing the driving rod 803 to also stop moving, so that the locking plate 6 stops moving, and the rotating wheel 5 cannot continue to rotate at this time. When it is necessary to release the limit on the rotating wheel 5, it is only necessary to rotate the rotating wheel 5 in the opposite direction, so that the driving card plate 804 that conflicts with the driving plate 808 is disengaged, so that the torsion spring 806 is reset, and unlocking is convenient.

[0031] like Figure 1 、 Figure 2 、 Figure 4 and Figure 6 As shown, in some embodiments, support rods 20 are symmetrically mounted on the two opposite side surfaces of the mobile cabinet 1, and a support seat 10 is mounted on the free end of the support rod 20. When the mobile cabinet 1 moves to the corresponding position, the support rod 20 can be rotated so that the support seat 10 on the support rod 20 contacts the offshore platform, so that the four support seats 10 are distributed in a rectangular shape to increase the support area of ​​the mobile cabinet 1, thereby making it less likely for the mobile cabinet 1 to tip over during accidental movement.

[0032] like Figure 1 、 Figure 2 and Figure 4 As shown, in some embodiments, the support seat 10 is rotatably mounted on the free end of the support rod 20, and two limiting plates 11 are symmetrically constructed on the support rod 20, which are used to limit the rotation angle of the support seat 10, such as Figure 1As shown, the design of the limiting plate 11 can prevent the support seat 10 from rotating too much when the support plate rotates, resulting in the bottom surface of the support seat 10 not contacting the offshore platform after the support rod 20 rotates, thereby reducing the rotation amplitude of the support seat 10. In this way, the support seat 10 can have a good contact area on uneven ground, thereby improving the use effect. Preferably, a rubber pad is installed on the bottom surface of the support seat 10.

[0033] like Figure 1 、 Figure 4 and Figure 6 As shown, in some embodiments, a driving gear 12 is installed on the support rod 20, and the driving gear 12 is coaxial with the rotation axis of the support rod 20, and the driving gears 12 on the same side are engaged with each other. It also includes a transmission rod 13, and the transmission rod 13 is connected to two of the driving gears 12 facing each other. The design of the driving gear 12 is such that when one of the support rods 20 is rotated, the corresponding driving gear 12 will rotate. Because the driving gears 12 on the same side are engaged with each other, the other support rod 20 on the same side is rotated in the opposite direction. Because the two driving gears 12 facing each other are connected by the transmission rod 13, the support rods 20 on both sides of the mobile cabinet 1 are unfolded at the same time. Only one of the support rods 20 needs to be rotated to unfold the other support rods 20, which is more convenient to use.

[0034] like Figure 1 、 Figure 4 and Figure 6 As shown, in some embodiments, a mounting cavity 14 is constructed on the mobile cabinet 1, a transmission rod 13 and a transmission gear 15 are installed at the position of the mounting cavity 14, a transmission rack 21 meshing with the transmission gear 15 is slidably installed in the mounting cavity 14, and a locking member 16 for limiting the sliding position of the transmission rack 21 is installed in the mounting cavity 14. When the transmission rack 21 is moved, because the transmission rack 21 is meshed with the transmission gear 15, and the transmission gear 15 is connected to the transmission rod 13, when the transmission rack 21 moves, the transmission rod 13 will move. Therefore, when the transmission rack 21 is limited by the locking member 16, the angle of other support rods 20 is indirectly limited, so that when the mobile cabinet 1 moves toward the cabinet door, the support rod 20 will not rotate, thereby further improving the support effect.

[0035] like Figure 1 、 Figure 4 and Figure 6As shown, in some embodiments, an adjustment plate 18 is horizontally rotatably installed in the installation cavity 14, and a movable groove 19 is opened on the top surface of the adjustment plate 18 along its length direction. A column 17 tangent to the movable groove 19 is constructed on the transmission rack 21. The adjustment plate 18 is located near the cabinet door of the mobile cabinet 1, and the adjustment plate 18 is located below the cabinet door of the mobile cabinet 1. The locking member 16 is used to limit the rotation angle of the adjustment plate 18. That is, when the adjustment plate 18 is pulled, the movable groove 19 will move because the column 17 slides tangentially with the movable groove 19. Therefore, when the adjustment plate 18 moves, the column 17 is forced to move in the movable groove 19 through the arc of the movable groove 19. Relative to the adjustment plate 18, the column 17 moves in the movable groove 19 and rotates along its own axis, thereby moving the transmission rack 21. The design of the adjustment plate 18 makes it more convenient to move the transmission rack 21. The adjustment plate 18 only needs to rotate slightly to expand the multiple support rods 20, and the adjustment plate 18 is located under the cabinet door of the mobile cabinet 1, which does not affect the staff's normal use of the tools of the mobile cabinet 1.

[0036] like Figure 4 and Figure 6 As shown, in some embodiments, the locking member 16 includes a connecting block 1601 constructed at the free end of the adjustment plate 18, one end of the connecting block 1601 is located outside and is vertically rotatably installed with a locking plate 1602, and a convex plate 1603 is constructed on the mobile cabinet 1, and two locking grooves 1604 for the locking plate 1602 to be clamped are provided on the convex plate 1603. When the adjustment plate 18 is rotated to expand the multiple support rods 20, the locking plate 1602 is rotated at this time so that the locking member 16 is clamped in the corresponding locking groove 1604, thereby limiting the angle of the support rod 20. The two locking grooves 1604, one is used to limit the angle of the expanded support rod 20, and the other is used to limit the angle of the stored support rod 20 (such as Figure 1 shown).

[0037] like Figure 2 As shown, in some embodiments, there are two connecting disks 2 and two rotating disks 3, and there are two rotating wheels 5 on the rotating frame 4, which are symmetrically distributed. The two connecting disks 2 are symmetrically distributed on the bottom surface of the mobile cabinet 1. The design of the two rotating disks 3 increases the number of rotating wheels 5, thereby increasing the friction area with the offshore platform when the mobile cabinet 1 moves unexpectedly, making it easier to brake the mobile cabinet 1.

[0038] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
